The Huizhou 26-6 discovery in the eastern South China Sea is expected to be the first mid-to-large sized condensate oil and gas field in the shallow water area of Pearl River Mouth basin, according to CNOOC Ltd.

The structure, in Huizhou Sag in Zhu1 Depression lies in average water depth of 113 m. The discovery well, HZ26-6-1, was drilled and completed at a depth of 4,276 m and encountered oil and gas pay zones with a total thickness of 422.2 m. The well was tested to produce around 2,020 b/d of oil and 15.36 MMcfd of gas.

The successful exploration of Huizhou 26-6 is the first time that the company has achieved commercial and highly productive oil and gas flow in buried hill exploration in the eastern South China Sea, marking an exploration breakthrough in Paleogene and buried hill complex oil and gas reservoir in Pearl River Mouth Basin, and further proves the exploration potential in the new field, the company said.
